This is an excellent start and one which I truly believe in.
One comment though: this document assumes that all transactions will
be done using XML/SOAP/Web Services (I understand the connection to OASIS). In
this respect, we are already assuming that each actor has enough bandwidth to
support such transactions, right? What are the provisions for bandwidth
Again, this is an excellent start and thanks for putting the

Subject: [smartgrid-interest] Draft Charter - Energy Market Information
I've attached a draft charter for the proposed OASIS Energy
Market Information Exchange (eMIX) Technical Committee.
This TC is intended to address the prices, market characteristics, and other
information for energy trading, buying, and selling. I was inspired to start
working on this from discussions in and around the NIST Building-to-Grid and
Industry-to-Grid Domain Expert Working Groups, and continued interest from
first round reviewers and from people attending GridEcon 2009 in Chicago (http://www.gridecon.com -- slides are
available on line at the agenda link).
From my perspective as an enterprise software architect, this fits into a
simple three layer stack with interoperation protocols (how to
communicate) as the fundamental layer. I put the Energy Interoperation
TC/OpenADR work here, with parts of the message payload in the next layer.
The middle layer is what is communicated -- for markets, things
like price, quantity, units, time (of use), and characteristics of the energy
sold -- from source (e.g. gas-fired plants, coal, solar, coal plant with
scrubbers, wind) to derived information (e.g. carbon data), and also trading
information (is this a bid, a price quote, an accepted transaction?).
The goal is to create an XML vocabulary that can be used in a broad range of
market exchanges with minimal differences (and where there are differences,
arranged in a simple way) for the various consumers of the information.
The third layer is the market design and definition; since markets have varying
degrees of complexity I'm leaving this alone for now :-). This is a potentially
complex area, and an interesting one. Accordingly, I'd like to carefully define
the EMIX work to focus on layer two.
I invite you to participate in a discussion on how to improve this charter, as
well as the sorts of characteristics that are important to energy markets.
If you would like to be listed on the charter when submitted as a supporter,
please contact me or Toby Considine.
